Haha. So let me get this straight. You obviously have to wait for the glue to dry. So this dude went into the stall, didn't look at the seat or didn't notice anything on the seat and sat down. Then he had to have felt something moist on the seat, but instead of standing up he said fuck it and just sat there and finished his business.
I inspect the hell out of public toilets before sitting down.
Good luck with boosting it. They do sell a supercharger for it, which last time I checked costs around $9K. If he's looking to go fast, buy a B5. Besides that he's going to spend about $2-3K to make 20hp or so from a chip and exhaust. They do sound good though.
My iphone tech knowledge is slim, but it sounds like you flashed the ipad's radio (aka baseband) on an iphone, so now you need to flash the iphone's radio back on the phone...
I'd wait for a second opinion though.
KBB asks for your location, NADA does not. NADA give me the highest price, so I will be using them from now on when selling, and Edmunds when buying.
EDIT: There is some more customizing you can do on Edmunds, and it ended up being the same as NADA.
