Went to Preston Hall BMW bodyshop today. Met a friendly estimator who came out and had a look at a rust bubble on my E46 just below the boot lid on the main body...
He explained the enitre rear bumper would have to come off and then they would sand down the rust bubble and then respray the whole back lip. After a bit of talking I managed to get a quote for £150 including VAT (he originally wanted 150+VAT) and agreed to buff out a few scratches for me
Does this seem like a good price for this bit of work or can it possibly be done cheaper?
