The list of sports car Holy Grail includes the Mercedes- Benz 300 SL Gullwing coupe. It may even be at the top of the list. At the top of any megacollector’s list of must-haves should be this all-new CMC 1:18-scale beauty. Hand-constructed of 1,817 separate components, this is truly one of the best diecast cars to be released in the past year. The fit and finish is worthy of Pebble Beach accolades. The engine looks so remarkably real you’d swear it could start. The operation of the opening doors, hood, trunk and steering is precise and as perfect as any seen in these pages. Prices for a real 300 SL Gullwing coupe have reached into the millions of dollars. The CMC-scale version looks like a million as well, but is listed at a very modest price. Like all good things, the supply is short and demand will be high.
