100% if not a all new massive Fullsize then yes a sedan and remaster or refresh of moonhawk will be good, maybe barstow to
I don't think that'll happen in 0.39 (spring updates are usually reserved for Euro/Japanese cars, like the FCV, BX remaster, Hopper, eSBR, Sunburst remaster, and K/800 refresh), but the LeGran did get a remaster in 0.22, so it's a small possibility.
I think the Moonhawk and Barstow will get a joint remaster. Muscle madness for March or something goofy like that. I enjoy every beam update, but I know people get tired of utility vehicles and props, and want a good car that they can do racing, drifting, dragging, rallying etc with, all on the same platform. So I think the devs understand that too.
We need ETK I series remaster, with new interior (based on Bmw E34 interior), more engines, like diesel I6 2.5, 5 speed AT, 4l V8 (Like the M60). New gauges with 280 km/h or 300 km/h speedo. Maybe V12 for Renshpect model. I know, my inglish isn't best.
The SBR4, as well as the I Series, is being slowly remastered, and the Hopper has a great chance of being remastered. As for the Moonhawk, I'd say its remastering will be on the level of the Legran or the Burnside, but since it's a car from the 60s/70s or 80s, it's very likely to be on the same level as the Burnside. But that's just my guess, but who knows, it's probably reality, let's go
