Hi
I'm new also and saw your email and thought hey that looks familiar.
I bought a 1997 GS300 in august, within an hour it had overheated. So I had the water pump and radiator replaced (as the radiator looked passed it) then a week later the new radiator blew to pieces. I took it to a local garage who dismantled it and found the head warped (who bought a lemon then) I has the head skimmed and bought yet another radiator and it was all put back together and off I went. Next thing was an oil leak to end all oil leaks within a week I had used all the oil in the sump so back to the garage it went. to cut a very long story short the block was warped and I have had to buy another engine SO the 3 grand car I bought off of ebay from an Audi specialist garage in Newmarket has cost me around 6 grand so far.
