Better & Cheaper than an E200 MMC
Which model of 200MMC? An 11.8 meter with 6.7L engine would cost significantly more than an 8.9 metre with 4.5L engine, I'd imagine.
I was going to comment "if you're comparing as like-for-like as possible" but even that isn't particularly close; the B8RLE chassis obviously has the roughly 8 litre engine and as far as I'm aware only comes with a 6-speed gearbox, chassis available in various lengths. Whereas the 200MMC in the various lengths up to 11.5m, as far as I'm aware only comes with a 4.5 litre engine with either the 4-speed or 6-speed gearbox? Except for in 11.8 meter length which is the 6.7L engine but then that is only available with the 4-speed gearbox.
So in short, thinking about the 200MMC in comparing it to the B8/Evora product, your options are either match gearbox but with a smaller engine on the MMC, or (roughly) march engine size but with a smaller gearbox on the MMC. So I guess in both those ways, the MMC is inferior to the B8/Evora, and yet according to this thread is still more expensive?
(Apologies for the rambling and for if any of this comes across as accusatory; I'm not trying to accuse anyone of anything, I'm just very interested in the topic!)
