I bought a mk3 8v GTI last week and was getting quotes in the region of 800-1000 minimum to insure third party fire and theft. I'm 25 and had 5 years no claims, contacted contacted my current insurer (Equity red star) with who i had a month left before my poilicy ended and they told me they wouldn't insure me on a Golf GTI full stop. I was pretty pissed at that point, as until then in my eyes they had been a good company. Anyway i contacted Greenlight after seeing them recomended on here and they quoted me £379 for a years TPF&T, which was around £300 cheaper than anyone else. I also explained that i had problems with my current insurer, getting my 5th year no claims and that I couldnt wait because i already had a buyer for my old car! After a few seconds on hold they said that they could give me the same quote price for 4 years no claims, so i called up Equity red star and cancelled straight away lol
Also i forgot to mention the quote included telling them that it is lowered and has 17s on.
So overall i recomend them to anyone for being helpful and giving a great quote!
