7 rules for a successful project car

You have a car. You want to make it into something better–something yours. Welcome to the world of project cars. 

Each project car starts with a dream. Or a car. Or a dare. 

Some projects cruise to victory. Others, well, less so: Ambition runs out, life gets in the way, interests and tastes change. Witness all of those incomplete projects offered at fire-sale prices, the time and money rarely if ever recouped. Bring a trailer and all that, right? 

Project cars have fueled this magazine since its debut some 40 years ago. We’ve had a lot of winners but also learned some tough lessons. 

What separates the success stories from the rest of the pack? Sometimes it all comes down to making some hard decisions–and asking some equally hard questions–early in the process. 

You can do this, though. As with most anything else, a little thought and planning can often make a world of difference. 

Know Exactly What You’re Committing To

What’s your goal and your vision? Heavy stuff, right? We see it often. People run headlong into a project car and, after sinking a lot of time, money and cussing into it, wake up one morning with an epiphany: What the heck am I doing here? 

Then they’re stuck with a difficult decision: Sell the parts and pieces for pennies on the dollar or carry the albatross to completion. Neither option sounds fun, right? 

How about starting the process by being honest with yourself? Does this project work with your reality? Will it work with your family’s reality? Your location? Your physique? Your physique in five or 10 years? Will anyone else in this world want the car after you’re through with it? 

Does your project have a clear goal–like, simply, why do you want to build this? To go racing? To create a cool daily? To fill a hole in your heart? Because the others on the GRM forum egged you on? All valid reasons, but just make sure you’re fully on board before committing.

Budget Your Money and Time

Have you priced paint lately? Or, really, anything? You’re not going into a project without setting some sort of a budget, right? Whether you’re using Excel or the back of a napkin, work out a basic budget for this endeavor–and then double it. 

And in today’s fluctuating market conditions, do you have contingency plans? What if key components get more expensive, experience delivery delays, or simply disappear from the market? Then what? What’d we learn in scouting? Be prepared. 

We tend to work with trusted partners we can trust–and yes, trust is purposely mentioned twice in that sentence. There’s a reason we have certain friends, shops and vendors on speed dial, for example. (And when the GRM forum isn’t fueling the Bad Decision Triangle, it can offer helpful info, too.)

The other part of that all-important budget: time. How about working toward debuting the car at some sort of an event–could be a major race or just a local show–and working backward from there. Set due dates for completing the major steps, and of course, don’t forget to celebrate those achievements. (Treat yourself.)

How’d you like to take a shortcut to summertime drives over years spent in the shop? Would you get more enjoyment out of the car by simply buying a good one that you can start enjoying now? 

Yes, the buy-in will likely be higher, but can that cost be justified by being able to enjoy it today instead of building it tomorrow? Some people prefer the thrill of the build, but many of us would just like to get out there and drive. 

Read the Rules

Building a race car? Have you read the rule book? And how set in stone is that rule book? Nothing worse than getting halfway through a multi-year build to encounter a rule change that renders your car uncompetitive before it even hits the ground–or even worse, makes it ineligible to take the green.

Make Space and Insure the Car

Where are you going to build this? We’ve seen some cool dorm and apartment parking lot builds, but that’s not always ideal. 

You have a dedicated workspace, right? And if you’re starting from scratch, flip ahead for tips on turning a typical two-car garage into a productive home shop. We’ve built some cool cars out of seemingly humble workspaces. 

Even while the car is apart and not running, is it properly insured? Why do you care? What if something really bad happens? Your homeowner’s insurance isn’t likely to cover your disassembled project, yet specialty insurance–check with the classic car carriers–will often cover a non-runner. They might insure your tools and equipment, too.

Buy What You Can Handle

We all know the hero stories about a guy who dragged home a car that had once caught fire and was put out with rust–and totally resurrected it to showroom condition. 

Do you have the skills, time and connections to do the same? If the answer is somewhere between “perhaps, if I get lucky” and “no way, bro,” then how about following some sage advice offered earlier: Start with the best example possible. You’ll pay more at buy-in but increase the odds for success.

Start a Routine and Make Checklists

How to get to that finish line? Are you willing and able to put hands on the car for half an hour each day? (If the answer is no, then a major project might not be for you.)

Don’t forget to budget time for the all-important sorting, too. There’s a big difference between a car that’s fully sorted–absolutely zero issues–and one that’s 95% of the way there. Fix that clunking exhaust, sticky throttle and loose driver’s seat before they have the chance to sour the entire experience. 

Checklists and notes are your friends. Make those lists visible, too–maybe on a big whiteboard in the garage?–so everyone knows what’s going on. There’s nothing worse than blowing up your new engine because no one checked the ignition timing before that first shakedown session. 

Check In With Yourself

Take a few to periodically reassess things. Has your vision or life situation changed? Is the project still heading where you want it to go? Is this what you really want to own? Can you accept one more heartbreak? Are you fully committed to taking this one to the end zone? 

Make sure this project is still for you, and don’t be afraid to abort. Know when to punt so you don’t spend good money after bad. 

And as we said earlier, don’t forget to celebrate those achievements. This should all be fun.


Be true to yourself, too. We’ve done cool, rewarding project cars that didn’t involve a mill, lathe and hours of fabrication. The big goal? Keep it all enjoyable. Photograph by David S. Wallens

"Don't be afraid to abort"

This is the single best piece of advice ever.

I recently ended up with a friend's Yamaha RD200 race bike project that had been sitting for 40 years. Back in the day there were loads of trick parts for it.

There was huge sentimental value for me as my friend passes away a few years ago.

After assessing the remains it was clear there was so little left, as well as a large portion of it being scrap, that I would never finish it. Ipassed it on to another friend so he could use the few remaining good parts.

The sunk-cost fallacy can be a heck of an influence.

Persistence gets it done.  Our average project time is 5 years.  Yes, it is a long time, but we try to do things right and only have a limited amount of time to work on it.  I am building projects with my friend of many decades - the build process, figuring out how to do something, talking about how we want it to work and look, etc. are big parts of the project process and satisfaction.  And so is driving when it is finally done.

I would add: Just because it runs fairly well, doesn't mean that it still won't require a lot of mechanical work. My latest project (67 Mustang vert) is kicking my but, inspite of running really well when bought. On the other hand - the prior project, an MGB that hadn't run in 14 years was a piece of cake.

A non-car guy buddy of mine recently told me he wants to get a 70s Corvette thats "mostly restored" and basically said our other buddy can help him maintain it, who also has projects, family, etc. All I could say was cool, (I'm tired of being the "well actually" guy)

Don't be afraid to abort!!!

That may be the best advice ever. Sometimes a project just doesn't work. Move on before you spend more of the limited number of days that you have on something that is eating your wallet and your soul. I just sold a refit project on a 100' steel boat that just became more than I could manage. What should have cost $75K all in was going to end up in the $125K zone. I got lucky and got my money out on the sale. I am going back to projects that fit in a garage and go fast.

Have as much money as you have time and have as much time as you have money. Have lots of both!
