Oh I love this kinda talk...lol I can do a lot of stuff on my 33 year old car, could even do tune-ups on it back in the day. But the engine is a highly computerized, recombulutin, fancya*sed, high foulutin piece of machinery that gets hooked up to another computer to get repaired... Happy rainy Saturday...I can still do the bulb changes but I have to remove the whole units now so a much longer job that it used to be.
