Some of the happiest moments of my childhood were getting a holly six-pack dialed in perfectly on my old Javelin... And balancing a six-pack is tricky as hell.. ;-)
I'm a FIRM believer in fix-first... Too many people treat cars as disposable... and I maintain that keeping a 60 year old classic on the road is better for the environment than any new car... We (the world, not just the US) produce nothing but crap these days...cars have a life-expency of about 5 years, 10 at the outside (if you're a non-BMW built Toyota that is)
My 2014 is 12 years old and still runs like it's brand new... I'll get another 15 years out of it easily... And when the engine dies, I'll replace it.
The only thing that kills cars permanently is rust..rust is the only true killer.
