Retro,
Have you decided whether you want a real Lotus, Caterham or ?
Within those decisions for Lotus, do you want originality or restomod like shown in Classic Motorsports with stroker crossflow, 5 speed, etc.?
Within those decisions for Caterham, early or late, live, dedion axle, or independent, kent bases, zetec or duratec?
Lots to consider
