Just to point out a dealer will not have £2k across a used car anymore. Very rarely, used to work of around £1500 Martian prior to costs 10 years ago and the market is very different now. OP if you want some genuine advice about the price of the vehicle chuck me an email I am happy to help. Not willing to divulge what o do for a living on here, but always happy to help a fellow singletracker.
The used car market has changed dramatically of late, dealers no longer sell into their local area and compete for first page on auto trader so drive prices and margins down. F&I income often suplimebts the lack of front end margin now so you can get better deals if you take the dealers funding package, they even can be competitive as their commission is both front and back end loaded.
Again if you want any help with pricing drop me an email and I can do some homework for you.
