Draw backs are
you can't leave it anywhere
depending on your age insurance can be pricey
sourcing spare parts is getting difficult, particularly body panels
as said gets very expensive when you want big horsie power
I have to disagree with my colleague above, cosworths are not everyday cars imo, they are toys which are best used ocassionally
but all that aside

they are cult cars and have an iconic status, they are very tuneable, fun to drive, deal with most things out on the road, no matter what people are driving they always want to have a go with a cosworth

do it

you won't regret it
