Had my V6 GTV for about 7 weeks now, love it but it's starting to give me some trouble. When I first got it it took forever to warm up, sometimes it wouldn't get above 70 degrees. Thought it might be the thermostat but then it seemed to get better.
The last couple of times I've been in it it went sailing past 90 and sat at around 110 - 120 in traffic, the fan may have come on but it didn't drop in temperature and yesterday it got to about 110 again after only a couple of miles.
What's this likely to be, water pump, thermostat or radiator? I need it fixed but scared to drive it too far in case it gets too hot and everything turns expensive so I need some trustworthy independent near North London.
