Sorry not to be in touch, but what is an SMBT?
In terms of weight, some of my past vehicles have included:
TVR 1600M 850kgs?
Nissan 200SX 1,249kgs
Nissan Primera 1,300kgs
MG ZT260 1,770kgs (ouch!)
Peugeot 107 850kgs
Peugeot 309 900kgs
Volvo XC70 (P2) 1,714kgs - currently sitting outside looking unloved
Tesla Model 3 1,847kgs (ouch, but it does carry c.500kgs of batteries everywhere)
I was quite taken aback to find an e-tron weighs over 2.5 tonnes and an i-pace 2.2 tonnes...
