My brother and I both had Mi16 205s, both had engine dramas eventually after years of proper abuse and neglect

My brother's spun a shell at the Ring, and mine did the same at Donington (the same day my Cossie also broke it's gearbox again at Donington

)
Think sadly the Mi16 lump is prone to it.
Great cars, really handle well. My car had the Mi16 box, my brother's I think was the 1.6, as his shot off up through the gears better than mine, but I could get my speedo off the end of the clock nicely
He did loads of work to his, but I think his best mod was the Quaife ATB diff he fitted, especially if track work is your plan.

2 tow trucks waiting to collect my Cossie and 205 from National Day 06:
You know you've got an unreliable car when you have to get towed 550 miles home from the Ring...... by a Cossie

My ropey Cossie dragging my brother's 205 home. That was a good fast run to catch the ferry, I think we may have nudged 90+
Mine got well used in a local sprint race on a go kart track:
Thought I had loads of good pics of the Pugs racing together, but can't find them. We used to drive round bumper to bumper at Combe and the marshalls kept telling us off for being too close
Great fun little cars!
