My first CRX back in about 2000 was a 89 Y-49 Si...quite stock, with 104k miles on it. I paid $3,000, if memory serves. I dumped a ton of money into that one, DOHC ZC when the stock engine blew at 135k, WW kit, full repaint, CF hood, lots of bits and pieces. I probably put a good 50K miles on that car. Later sold to my old roommate, who sold his Blade Silver DX with Mini-Me swap to buy it. He ended up getting a newer Tibeuron and sold the yellow CRX to some foreign dudes from Chicago. He was later contacted by the Wisconson State Police when the car was found abandoned in some random parking lot probably 6 months later, still registered in his name (they never registered the car or got plates for it). He gave the cops all the info he had on these dudes, and considered going to get the car back, but the fees he would have had to pay the wrecking yard that held it the whole time that they tried to contact him (he changed phone numbers after selling the car), and it wouldn't have been worth it.
While that car was being painted, I picked up a silver 87 Si to drive around as a daily/winter beater. Paid I think $1000 or 1500, totally stock. Drove the hell out of it and later sold it to my old boss for $900, he wanted a car that got good mileage for a long commute he was making at a new job. Drove the hell out of it until something went wrong, rather than having me fix it he just gave the car away to someone he knew who was badly in need of a car (nice guy).
After the 89Si and the 87Si, I briefly drove an AWD turbocharged 1G Talon. Fast, but a pain in the ass and it wasn't a CRX. Sold that and picked up a 91 Integra LS with non-VTEC B18...no rust, black with tan interior, had under 80k miles when I got it. I think I paid $3200 for it. It was like a CRX but bigger, with power windows and all that jazz. Pretty nice car, I kinda miss it sometimes. I traded it straight-up to a kid from Honda-Tech for my current CRX, a 91 DX with SOHC VTEC ZC swap, Si seats, and some other mods. The car was a little noisy and rough when I got it, I'm slowly making it a little more comfy. The car itself has 190,000 miles on it, but it's virtually rust-free (the car has been repainted black) and in pretty good shape overall. Lots of compliments on this car, and it's getting some goodies right now that I'll post about soon.
