Hi Lanwarrior!
2 sections to my post here
first one - I'm about to save you a good wedge of money for the car and the fact your better half is wheelchair bound. I employ a member of staff (he's my Programmer!) who is in a wheelchair - he can drive and from a conversation with him recently, he tried ALOT of different cars that he felt comfortable with, easy to get his wheelchair in and out of. The 'actual' car didn't matter so much - just had to be a 5 door hatchback, as his wheelchair would be transported where the back seats are. He came up trumps with a Honda Jazz Automatic. The steering and pedal modification certainly didn't run into thousands! - I will ask him on Monday what the cost was etc. I do seem to remember he has the 'pull' for 'pressing the accelerator and 'push for the brake' - again I'll need to look at his car on Monday (or sometime next week!) to be better able to report to you.
Of course, I understand yoru wife's disability may be different to my staff members and to effectively allow her a smooth transport system within a car may cost alot more - but from what you've said just now, it 'seems' to be pretty much the same as my staff member. I'll also get you a price he paid for the conversion assembly (off the top of my head I recall a figure of £700-800.
second point - your budget. There are other posts which I've posted in where I listed many of the 'hidden' or 'less thought of aspects of personal finance. I'll have to write up an article and see if the board admins will make it a sticky.
however, I'll list some of the points here
1. Budgetfor Savings
2. Budget for Price increases
3. Budget for utility price increases.
4. Budget for Insurance (home, life, contents, theft, buildings etc) & their possible hikes.
5. Budget for Council tax hikes (I think your current 70 quid is a little low - my2 bed flat/apartment is I think £84/month and like Redbridge is an outskirts of London area, so is Slough, so roughly comparable - I'd say bump that up to around 90-110/month then factor in the inevitable increases)
6. Budget for Unexpected Maintenence costs
7. Budget for Emergency repairs/trouble
8. Budget for a Emergency 'cash' stash
lastly, budget for variances in all the stuff you'll buy, Petrol, phone bills, utility bills mainly can vary substantially month to month (beleive me, I speak from experience after a phone bill went from £23 every month to £600! - I forgot to check if the access number was included in my calltime bundle, it wasn't and I $hat myself when that bill popped through!)
Of course, there are other elements which you personally in your lifestyle only know about (holidays, impulse buying, clothes, etc etc etc) and some of the above I've mentioned you may have already bundled into your misc item listing.
Overall though, 49K +8.5K total £57.5K is a top notch salary, UK average is 23K (and the REAL way to compare is the median average, which makes the UK's median salary at just over 17K - I think I should start to quote the other financial sites I read these figures from soon!!) which places you firmly in 'top dosh' earners. I think with you keeping a good eye on your finances, you'll be very comfortable.
It's fri night/sat am and it's 140 am... I've had my fun for the evening, im off to sleep! I'll start writing up that article maybe later today!
Hope this helps - Cheers! DtM! West London & Slough UK!
