Love you choice of cars. I had a 93 300ZX TT that I sold before we had our first child in a fit of responsibility. The worst car decision I have made to date.
When mine acts like that the fuel hose has fallen apart in the gas tank. Once a new pickup line is installed with the ceramic filter on the end of it, all is well. The ethanol eats the rubber tubes.
The exterminators around here put a net around the opening to catch the bats as they exit, fix the hole and then after payment release the bats. Then the neighbors get bats. They charge an insane amount of money to do this.
I have a single door on a two car garage that buckled when lowering. The door guy came out and riveted in a strut that spanned the length of the door to support the weak area. That was over a year ago and it is still fine.
Re: what did you do in your garage today?
Set my front ride height, tightened all of my radiator hose claps (had one blow off earlier this week), filled the cooling system and let it cycle several times to get the air out.
I know someone that make apple pie moonshine. It tastes just like apple pie, dangerous to drink, it is so smooth. That should be a big seller for you, good luck.
Wow, is there an epoxy coat over that tile? How slippery is it? I had pretty much decided there was nothing that could be done to my stained cracked floor other than racedeck. The idea of tile covered in epoxy is tempting.
