Same here. I have an excel spreadsheet with date/mileage/cost of any maintenance or modification I do. I hate wondering "when did I change my front brake pads?". I started doing this with my last daily driver and it was very helpful. I also keep all my receipts but it's easier to look at a spreadsheet.

I don't have an Excel spreadsheet but I DO SCAN all my work receipts, purchase receipts in and keep them

Great minds think alike... in stats, records, and silver stripes.

Hey i love the silver Stripes, but I wish I had time to do all of calculations, But props to you guys! I know I get 19.4 MPG around city driving and some HWY!

I've got the maintenance spreadsheet going with mileage/cost/item serviced.

I've got a phyiscal notebook labeled "2010 Mustang" with every little piece of related ephemera & all receipts to my ride and ancillary purchases. Original window sticker included

I've got a "2010Mustang" directory on one of my partitions with hundreds of megabytes of data (includes some 300+ files in 70+ subfolders). This has everything 2010 Mustang related (PDFs of Ford documents such as the owner's manual, TSBs, scanned copies of receipts, pictures, vendor information, catalogs, "how-to" info, etc.)

Plus I've got plenty of gas receipts with the MPG written on the back of each.

What I don't have is the current mileage at each fill. Now that I've seen the great data which FordEngineer and PSU Ben posted -- I'm pissed I didn't do this from day 1!

For me, this is partially what makes owning a car easier and more enjoyable overall: instant access to needed knowledge about its history and what you've done to it. Like AJ mentioned, I too started doing this with my last ride.

'ditto' I keep a folder in my car with pictures, stats, window sticker, bought just about every dealer brochure, etc. May come in handy when I take it to some Mustang shows, you never know. What I'm trying to find now is a nice 1:18 scale model that isn't a convertible. Haven't found one yet.

They make 'em in the standard "Hot Wheels ®" size (is that 1:64? I'm not a Hot Wheels aficionado.) You may already have known this -- see the 7th picture here:

Tiny 2010 Mustang

I got one for the holidays from the g/f -- as did the poster of the above message. But I suppose they're a bit small for car shows.

i don't go nearly as detailed as you FE, all I do is write down miles driven prior to the fillup, and write down the mpg for that fillup, all on the receipt.

I think I'm averaging around 23mpg overall in 50/50 stop-n-go/highway driving, higher mpg during summer and lower during winter.

Tylus

how are you guys getting such good MPG's?

I'm running 14.5-15 mpg...period. I do drive fairly sprited I guess
I used to do the data tracking in Excell, but everytime I deploy the wife invariably fails to keep any reciepts or mileage when I'm gone.

so I have gaps...sucks
