IMO No they aint that bad really. Esp if you lookin at a gt as most of them are still fairly new! Iv had two g7s one 140 and nw a gt never had any issues at all! As long as they have bin well looked after I.e full toyota history etc or low mileage then you will be fine! I don't even see many at work with issues. The 140s burnt oil but you won't have tht issue with a gt being the 190 engine. For how many people that have them, a few on here have had a few horror stories but it will seem that way as they all want advice, but on a whole they run ok! Pay decent money for a minter defo worth it. As you will always as with anything 'get what you pay for!'
