I took it to a garage for a quote and they let me look under the car whilst it was lifted up in the air.
I need a new mid and rear section for sure. However, the front-mid section of the exhaust are so rusted together than I think damage will occur. The front section for the part alone is about £45+vat but I would rather a full exhaust rather than replacing the middle and rear now, only for the front to go in 6-12 months time.
The best quote I have had is £142+vat, which seams reasonable as parts alone are about £100+vat.
Can anyone confirm this is OK before I go ahead and get the work done?
