I wouldnt say it looks girly but its certainly not agressive or the sort of car that appeals to a young driver.
I think my del sol looks sportier sitting beside my dads MGF, mine certainly has the sportier ride, but then again mine is modified and his isnt, perhaps if they were stock for stock it might be different.
Whatever anyone says about ehm they still have been really popular and have a reasonable turn of performance, youve got to do alot of modifications to an MGB for them to go as well as a stock F, all that and dad can get 45-50mpg.
The TF really isnt a new model anyway, its only a facelift on the MGF
