When everyone is getting ready for a long road trip, it's always a good idea to think about the supplies you keep in your car. I usually keep a bag in the back of each of my cars with pretty standard emergency gear. The bag has gotten a bit larger for the MINI, over the years... That was my old bag... the one for Rufus is slightly larger: Here's what's in it: A blanket in a water-resistant stuff sack (on left in top pic) A Slime kit (for tire repair) that I put in the driver's side boot cubby A sturdy bag (the red one, from Target, to hold all the rest of the stuff) Cash - about $25 in bills and $3 in mixed change (easily the most useful item) Glucose tabs and medicines (tailor it to your needs... I keep extra ibuprofin in the glove box) Tire pressure gauge A map of the area you are most often in Extra fuses A folding shovel Detailing supplies like microfibers, 303 protectant, Zaino Z6 (I'm a detailing nut) Water (at least a liter) Twine A mixed selection of Ziplock and trash bags Rubber gloves tissues (Kleenex travel packs do nicely) Jumper cables Duct tape Flashlights (one LED and one regular)\ A poncho A space blanket (foil blanket) - I used to carry a fleece blanket, but I live in a pretty mild part of the country... I went for space saving in the MINI, but my wife's car with a large trunk and my daily driver SUV still have a full-sized blanket. Often nice for padding while crawling under the car. A pocket knife First aid kit (the bigger, the better) Gasoline siphon Small set of tools Torx driver set and allen wrench set A wrench and a pair of channel-locks FRS radios (for club events) Tow rope bungies road flares (3 or 4, at least) - now replaced w/ a reflective triangle gadget My "I need to catch a stray dog" kit with dog treats and a slip lead (so I can help get the little ones home) I also keep a few MINI spares back there... a belt tensioner tool, a spare clutch slave (I had a bad history of burning through these... I never needed it myself, but I've given it to others twice), an extra serpentine belt and a lug bolt or two. If I replace a part before it dies and it is small and light, I frequently throw the old one in the bag (Ex: the idler pulley I took off a few months back). When going somewhere that I might do enthusiastic driving, I pitch my torque wrench and socket in there as well. I also have a spare bottle of oil under the bonnet, for top-ups.
