Our "new" 97 Miata

[CtrlAltDefeat]

My mom finally decided to get rid of her little red Miata so she gave it to me. Some points of interest: it has Konig wheels, a pretty well used interior, a replaced but now mostly ripped out rear window, nicks, dings and scratches expected on a 12 yro car, about 125k miles, rust in front of the rear wheels , and was kept in a garage without maintenance for a year... Seems to run pretty good still. I changed the oil (but not the filter since I already had the oil drained when I found out the filter is pretty much not user replaceable) I had no way to drain the gas tank like I really wanted, so I added some sea foam to it, and ran it to about 1/4 before filling it up with premium and some gas conditioner. The engine runs a bit smoother now, but since I have no real point of reference, I'll assume the amount of noise and vibration that reaches me in the cabin is typical. (the gear shift vibrates a lot but I think it's normal) I hope to fix/paint/modify it in the future, but in the mean time I'm more concerned with preventative maintenance and probably fixing the back window (somehow). My wife loves the car and has already named her Mia. If any one has any suggestions, I'd love to hear them... Driving the Yaris feels like a bubble on wheels after driving the Miata for a while...
