I remember receiving a car for TMCC14 (which I hosted) whose engine also had a 2v DOHC head. Even considering the fact that TMCC14 was set in 1995, not 2018 as CSR153 was, the overly primitive head configuration (which would have been more appropriate for the 60s/70s) was enough for me to reject it straight away.
And regarding that Proton…
Hang on, didn’t I see this car before? It reminds me of something I received while judging QFC19:
They’re both built on the same body set (though not necessarily in the same size) and share many of the same exterior design features, so it’s no surprise the Proton looks like a facelift of the Everlast.
