A high-mileage and extensively customized R8 is perhaps not the most advisable starting point, to be honest. As previously said, wraps can conceal problems, and in the case of BC coilovers, I can assure you that the spring rates are incorrect. If it has been well maintained and is reasonably priced, it may be satisfactory; nonetheless, you should allocate funds for potential issues (oil pump drive seals, rear arms, air conditioning, walnut blasting, etc.). Ricky's buyer's guide serves as an excellent starting point, and it is essential to thoroughly examine the service records to ascertain the maintenance performed.
