you drive a 1992 240sx..... you're comparing $v$ with a new vehicle..... that's a pointless argument...

A new mustang costs $40k... with $40 i could build a pinto that would destroy it... does that mean pinto>mustang?

Mustang > 240 $v$...

Compare your 92 240 to a 92 mustang....

that or compare what a silvia costed new in 1992 then factor in inflation and compare that to a new mustang....

however you add this up. Mustang > 240
