2.5 CDX sprung a leak on the last day of holiday in Devon, £600 recovery quote (I have AA cover now!), nursed it back to just past Salisbury filling up just over 6L of water every 20 miles. Finally dies when the layby I planned to stop in was blocked and had to carry on to the next, coasted into that one with no power and I discovered later an oil cooler plate with a 2" diameter hole burned in it! Recovered home for a much more reasonable £120.
Mk2 Capri burned out the clutch towing a scrap Beetle to the yard, pushed both back home.
1 week later the same Beetle had both nearside wheels fall off while on its 2nd tow to the yard, watched the first overtake me thinking "haha someone lost a wheel"
Finally got it to the yard.
Mk2 XJ6 lost a con rod through the block on the M40, covered all 3 lanes in a huge wall of smoke as it dumped its contents onto the exhaust. Recovered home.
And the icing on the cake.... MK2 1.1 Escort estate had the exhaust blow on the M3 just past Fleet, still mobile so decide to go to the next junction. Didn't realise that the gearbox gater was missing under the centre console and got gassed in the car, woke up heading up the bank of a bridge, steered it back down but just run out of space and ended up driving it down the middle of the crash barrier protecting the bridge. It then leant to the left and and dragged along the concrete with me finally veering into lane 1 and then bringing it to a halt on the hard shoulder. End result was a split sump, split gearbox casing, split petrol tank, split diff, front to rear brake lines ripped clear off and it looked like someone had taken a cheese grater to the entire passenger side. 3 fire engines, 2 police cars and 1 ambulance in attendance, the fire engines apparently spending most of their time trying to clear the mix of fluids as my car had none left in it!! Recovered to the yard, following week I went down picked up my sunglasses and walked away from it, nothing at all worth saving.....
