Okay, I took this out to try and fall back in love with it this morning. And I've failed. It's just aggravating me. So I've offered it to crapcarcollector again. I'm just going to drive my properly reliable 19 instead, as it's been sat in the garage since November just being started every 3 weeks and has never failed me yet.
The Tipo just needs that matrix fixing properly by someone who can do it, which isn't me. It's too good to just be run as it is. I've even sort of washed it, and put enough juice in it would get someone 30 miles to the local supermarket rather than the more expensive garage 3 miles away. I've dehumidified it slightly by leaving the window down to (the one that works).
