Dealer prices seem to be in the 25 to 30k region for this age M3W
Private sale, non-standard modifications, a bit tatty round the edges, 'novelty' paint scheme, The low miles indicates lack of use and potentially significant recommissioning costs. I'd probably expect a great deal less as the pool of potential buyers is small and dealer support for these cars is probably valued quite highly. Ask for 24 and settle for 20 would be my guess.
