What! You thought the old was small?
Well, I've worked on every Mustang made including some that weren't
and yup, the new one is big while the older ones were small. With the exception of the '71+which was bigger but didn't look fat like the new one does.
It isn't my fault you Europeans have goat paths for roads
j/k
Astro, you were driving a generic Mustang. Any passenger cars produced in the US are designed for the generic person. Obviously this person doesn't exist but the compromises made in production to get cars off the show room floor are there. After purchasing any American vehicle you need to tailor it to YOUR individual tastes. If they built the car to road race specs many buyers would complain the ride was too harsh (See the 1985 Chevrolet Corvette). If they built it for power, many drivers would end up in the weeds (See the Dodge Viper). Soooo, they build them for 'everyman' and let you take it from there.
I can assure you, the Mustang you were driving can be made to perform VERY well. It's still a low end budget car but it'll scoot and corner or whatever else you like. I've built or assisted in building many of these things and they respond very well to the tweaks.
I think the styling of the new 2005 car might be interesting enough to get a slot car made of the thing.
