Quick introduction as a new member with a 2011 Aygo 1.0 Petrol. I've been hypermiling for a few years previously with a Pug 206 HDi and then a Fabia VRS, and now an Aygo.
I loved the VRS but the insurance and servicing costs were becoming very expensive and my mileage dropped to under 6K for the last year I had it. And with new Diesels having DPFs which don't like 100% town driving I decided to make the switch back to Petrol with the Aygo. OK its a lot slower than the VRS but what I save on insurance (£250 a year) and services (£99 fixed price every 10K miles) pays for 6 or 7 tanks of fuel so I'm happy. Tyres are also very cheap - got a pair of good ones fitted for under £60
I haven't kept my averages up to date, need to start on Fuelly I suppose. I have had a tank to tank best of just over 70 but most averages are in the 55 to 65 mark which isn't bad for just around town (Edinburgh) with loads of jams. I'm reasonably happy with town driving being good for MPG but can't quite master motorways with the little car. The gearing isn't too bad at 22, the grill is usually blocked too - uncovered for the heatwave just now.
Other car in the household is a 2011 Prius which is Mrs Morph's. Mrs M doesn't hypermile but gets 50-60 in it and likes the auto gearbox. I can get it to 99.9 MPG quite often when I get a go (!) and we are thinking of keeping it when the lease runs out (its a company car) if we get a reasonable deal. Only thinking about it, the appalling interior rattles are putting us off a little.
Your figures (estimates) seem quite good so far, if you get that in reality I would not complain!
We have adopted a new family member - a dog who's owner is now deceased - so holidays, weekends etc. are going to be more family orientated plus Mrs M is more or less at the limit of her company car "personal use" miles.
