between me and my brother we have had ten renault 5s my brother still has two now as well as his series 1 5s just have a bad rep if you pay pennys you will get a shit one and it will break all the time same as anything else
as for the 5 against the rs how many rs turbos are in the 11s-13s quarter mile there are loads of 5s doing these times at pod so it all comes down to spec but they only way you will find out is by having a go , my mates 5 is rapid 270bhp and still a 1.4 beats me every time
