I'm in a similar position having just bought a 2006 Jazz with 122K on the clock and as I don't know the history I'm doing the following work....
I saw your thread, I paid 10x more than you did! :'( And it was one of the cheapest automatics I'd seen in the last few weeks. "Full Service History" but the last stamp was independent and like I said the CVT fluid is the wrong colour, so I can't trust the rest of it.
Something the previous owner did before I collected it was the airbag recall which was fixed under warranty. Dont know if you can maybe check if yours needed doing and if it was done?
If you use the GOV website to check the MOT history, it'll also tell you if there's any recalls out. Another Jazz I looked was flagged for recall, but mine wasn't, so I guess it's been done.
Worthwhile checking the cabin filter behind the passenger glove box, I use Blue Print filters makes a world of difference once replaced.
I bought one of those and an air filter last night ==b. Got Bosch ones, hadn't heard of Blue Print before.
Just remember, changing the bulbs in a Mk 1 headlight is a mammoth task and OSRAM cool blue intense H4 bulbs have a relatively short life.
I had no idea. Just looked up the Haynes video and I'm getting flashbacks to trying to change my headlights, blind and at arms length, through the wheel arch of my Rover 75. Taking the whole unit out may be best for sanity.
I put the car on my little ramps yesterday. No deep rot, but it will need undersealing. Got some surface rust on the arches too. Inside the arches were caked in muck. Pretty deep pitting along the bottom of the sill too.
For oil, I used the current 20% code on ebay to order 5L of 5W30 Ford Fuel Saver spec Mobil Super 3000. Bought a genuine filter to go with that too. Postman's going to be sick of the sight of me soon.
