    Here's a sure-fire method involving motorcycles, which can be bunched together in a much smaller space than cars and will blow up easier as a result.

    1. There's a motorcycle dealership in northern Alderny, you can find it on this map and set yourself a waypoint in the game: http://www.gta4.net/map/?lat=33.75&lng=-52.646484375&...

    (edit: Updated the link.)

    2. Call Packie and have him drop a bomb off for you nearby.

    3. Place the bomb on a car, and drive it into the motorcycle shop.

    4. There should be maybe eight motorcycles parked in this shop, use your car to pack them tightly together, preferably in a line.

    5. Once you have them smushed together, park your car on one side of the line.

    6. Jack another car, park it on the opposite side. This should bring you up to ten. Count and make sure you have 10 vehicles. In the comments, con2king suggests packing in a few extra cars, which couldn't hurt.

    7. You might not even need it, I didn't, but stand outside of the dealership with your rocket launcher and then call Packie to detonate the bomb.

    8. Everything should blow up real nice. If not, make use of your rockets quickly.

    EarthboundXTried it with the car bomb twice, didn't work. Did it again, but with a grenade, and a few rockets, worked then.

    frenchmau5Bike shop worked for me. Avoid being wanted by simply driving a car, already loaded with Packie's bomb through the window of the motorcycle shop and use the car to push the bikes up against the wall. Don't ever get on a motorbike and you don't become wanted oddly enough.

    A Dreadful ShotGreat solution. Got this without getting on a motorcycle or phoning for a bomb. Just pushed all the motorcycles into a group with a car, then placed three cars around them and shot it with my RPG. One shot and the achievement popped.

    1-There's a motorcycle dealership in north Alderny. Break the glass with any car and push all the motorcycles into the corner. Leave the car in the corner as well

    2-Get outside and jack another car. Park this in the corner as well along with the car and the 8 bikes.

    3-Throw a grenade or two into the corner. One should do it but two should guarantee that all of them blow up if you do it fast enough.

    4-In case the achievement didn't pop up, just run outside and shoot a car with a rocket launcher.


    ***Notes***
    -If you get on a motorcycle to move it, you will get a one star wanted level

    -At the very instant the grenade/s explodes, you should get this achievement. If it doesn't pop up, shoot a car outside with a rocket launcher RIGHT AWAY. Don't wait because you're not sure if you got the achievement or not.

    The video below shows another way of how to get the achievement. Very straightforward, credit for the video goes to YouTube user "TrexiZ"
