$10k for a cheap job, $20k for a good job, $30k + for a top job.
I think this is the right way to think about it:
ASSUMPTIONS
- No sheet metal work (no rust or big dents)
- Old paint is mechanically ok so car doesn’t need to be stripped to bare metal
- Dis/reassembly of exterior trim/glass by owner
- No respray of engine bay and trunk
- New paint NOT wet sanded and polished
- 3 stage paint
(1,2,3,4). Here near Boston we would expect to pay $10k for a nice 2-stage metallic color/clear coat paint job, appropriate for any modern BMW.
This is pretty away from what is appropropriate for a collector/show car. Many shops out here use water based paints as is done in CA.
Here are my estimates for variations:
(1) sheet metal work can run from $100 to maybe $70k? Obviously our E9’s are easier than an alloy car or a superleggera chassis.
(2) going to bare metal is +$4000
(3) this is a lot of work to do well on an E9. I’d guess +$3000
(4) +25%, plus $1000 for engine Removal/installation and $300 for the trunk R&R. Don’t laugh but it takes a bit of work to pull the trim, fuel tank, wiring, etc.
(5) $2-$3k to completely wet sand and polish the
entire car to remove ALL orange peel. Obviously you can scale this back to a budget target.
(6) +$1000
And, if I took the same car to 5 shops, I’d expect to find up to a 50% increase in cost. This variance is a combination of how well the shop is run/managed and how badly they want your business.
