Let me go ahead and chime in on this one. I decided it was more economical/smarter to get a car that gets better mpgs and whatever for cheap, so I got the cheapest lightest 5 spd RWD non interference car out there, the Miata.
After maintenance, I've spent 2 or 3 times what I bought the Supra for. Miata has been towed 3 times and left me on the side of the road looking for water to dump in the radiator a few more. I've never towed my Supra and the only time it left me on the side of the road was the night I bought it when the throttle set screw thought 3k RPM was a good place to idle. I unscrewed it back to about 800 RPM and that was that.
Last month was 2 years of me owning and driving the Miata, and with all of the problems it has given me (especially when the previous owners were an old couple) its just not worth it. The Supra is built better, much more comfortable, sounds better (especially with a venting type S and open wastegate), and just all around more reasonable. I am now coming home from college this summer to save up for a FFIM and FMIC so I can use the Supra as a DD again.
You'll come back. The Supra really is the best car out there. I could list why, but my post was already long.
