I took my car here a few years back and at the time i was very pleased with them. I took my car there to have the cv joints done and to have the muffler part under the bonnet fixed. This part had been welded by another mechanic to temporarily fix it till i could afford to get it fixed 2 weeks later. So i decided to take my car to carlines as i had heard they were good and cheap. I left my car there for the day and when i got back they had fixed the cv joints but said there wasnt anything wrong with the muffler and that other mechanic had told me a load of crap basically. As a female and not knowing much about cars i believed them. Over the next 3-4 weeks i continued driving my car thinking everything was ok with it. I soon found out it wasn't. when I took it to another mechanic after hearing the same noise i was hearing before my car was fixed he was very surprised and shocked. When he looked at the muffler part under the bonnet, the muffler was cracked and pretty much just sitting there by a little piece of metal and all the fumes had been coming back into the car. I actually went home that afternoon and became quite sick. I had a touch of carbon monoxide poisoning from driving around with car fumes in my car. So from that day forth i refused to take my car back to carlines and always tell people not to take there cars there.
