My best and fastest slot cars are my Plafit cars - they all run the same chassis with some minor adjustments for different car sizes, axle heights etc. These chassis run out about the cost of an NSR car to start with and you can add more with specialised parts and then you need to add the cost of the body so base price around $160 for a RTR car 1/24 car a bit less maybe for 1/32.
I figure with newer materials something like this could be done in a more affordable price range. With out the need to produce a new chassis mould for each car then that may mean the overall production cost is less thus the cars wouldn't need to be any more expensive to incorporate a adjustable universal chassis...
I find the chassis on cars vary so much that I sometimes was wishing that some companies just sold the painted body for half the price and let me do my own chassis.
Performance wise something like this walks all over the chassis in most RTR cars to me it makes sense to liberate the need to make a new chassis up for each new car which quite often gets messed up - this is also a lot better than a sebring or PCS chassis
