I upgraded mine during a previous sale to 84.4 (26/29). Only engjne, drivetrain & body lack the final upgrade. The cost of those last 3 upgrades (@30% off) would be 809 gold. The cheapest, though, is also the most significant; 126 for drivetrain #4. This is the only one of the 3 which gets my PR >80, which is required to finish Vertex Spirit. Completion of VS yields 32 gold, so my effective cost of that last drivetrain upgrade will be 94 gold.

Cost to FU these higher end cars rarely makes sense from a purely economics perspective.
