I've got my '99 Wrangler, which is currently my daily driver. A few parts have been replaced with more off-road-functional ones when they went, but being a Jeep, parts aren't going often. I'd like to help it on its way to a full-on rockcrawler a little quicker, but I'm content putting most of my money into my other car right now. I'll make sure my Jeep will get there, I've completed the bulk of work on the car, which will free up a little money and more time.
The "other" car is my '91 E30, which is fast becoming a Spec E30 car. It's still street legal for now, as I run HPDEs, but won't be much longer than that. Soon, it will need to be trailered from one track to the next. I was going to buy a pickup to take over some DD duty and towing duty, but my dad offered to let me use his Hemi Commander to tow when I need it.
I could draw up a huge list of cars that I would love to buy just to fix up, modify and track, but I've got most of my money going into the race car. And I wouldn't prefer to have one of those and give up on racing. I imagine when I've got more money, I'll put it towards another car, either moving up another class or getting into rallying. I don't really spend much on other things I buy, so at some point I'll have something street legal to drive up to the tracks (VIR is pretty close by), but getting racing is my current automotive priority.
