I agree with Troy. I live in Switzerland and know that the Jura offers a lot of wonderful scenery for photography. However for shots like these, you either need to use a telephoto and zoom into the car to force the perspective, or to use a wide angle and get close to the car. Another thing here is that you may want to consider getting some suction cup mounts to attach your camera to the car as you or someone is driving it.
Do some online searches for DSLR suction cup mounts, here is an example: http://www.filmtools.com/carmounts.html
Yes they can be expensive.
Or if you want to take photos of the car while it is stationary, choose a better background and hour of day. Midday sun is not really the ideal time for photography as the harsh light can bland everything out. Places like Lac de Joux, or Versoix/Montreaux parts of the Jura have wonderful scenery. Definitely loads of places to park your car and just wait for the perfect lighting. The season is late already but during the months of December, January and February, Lac de Joux gets frozen solid enough for hundreds of people to ice skate on it, it may be strong enough to support the weight of a small car...not sure.
What are the attributes of the vehicle you are trying to photography?
- sporty streamlined look
- being a car, you definitely want to show a sense of motion/speed
- a car has its own lights, you may want to consider doing some long exposure shots during low light hours, perhaps with rear-curtain flash sync
