This is the most luxurious car I have made so far in 4.2 - the 1995 Ventnor V12. Aesthetically, it’s inspired by the contemporary Bentley Continental R, but in a sleeker four-door format.
Engineering-wise, it’s powered by an all-alloy 400-bhp 6.0L naturally aspirated V12 driving the rear wheels via a 5-speed advanced automatic transmission and a geared LSD. It’s hand-built to order, hence the hand-made interior (which incorporates a luxury stereo sound system, plus a CD/cassette tape player). For maximum comfort, it utilizes air suspension with adaptive dampers and semi-active sway bars, tuned for a smooth ride with a hint of sportiness. The interior - trimmed in the finest genuine wood, leather and metal trim (exact colors being dependent on the buyer’s request) - usually seats four, but you can specify a five-seat configuration at extra cost.
I used 1 techpool point for the block/heads (to select aluminum/silicon as a material for both), 1 techpool point for the chassis (to unlock AHS steel as a chassis material), and 2 techpool points for driver assists (to ensure that ESC is available by '95 - I had it fitted to this build).
Obviously, such opulence doesn’t come cheap - the markets section of the overview tab shows an estimated price of $73,500 AMU - but anyone in 1995 looking for the most luxurious thing on four wheels could do a lot worse than the Ventnor V12.
(I only posted this after taking a look at the Primus Legacy above, and realizing that I wanted to - and could - do even better.)
