    AMAZING!
    Spent 6 fun hours building it!
    It wasnt so difficult, it turned out looking good and bigger than expected
    Nothing was missing and even got extra.
    Looks lovely on the shelf
    I recommend to all of you lego and car lovers 🙂

    Great build but pieces missing
    I thought I’d try something new and start relatively easy. Enjoy it right up to the last 10 minutes when I found I had 2 pieces missing.

    I can guarantee they wasn’t dropped or lost as I opened each packet into a plastic container.

    I feel really disappointed and now have to buy the 2 missing bits at a cost of 5.00 (best price I can find).

    With this problem I can’t honestly give it 5 stars.

    Toy of my childhood
    I am always fond of Lego as building block. Specially moving and working models.
    I was looking for this model and finally found. Complete with details. It’s more of a miniature model than a simple building block project. The best thing is with very reasonable price.

    Fun build
    A good quality Technic Lego build. The instructions, as always, are accurate and easy to follow.
    The end result is a good looking model.
    There are a number of stickers, which perhaps should have been provided as printed bricks.
    The drivetrain to the rear wheels seems very simplified, with only 1 wheel actually connected, and no rear differential.

    A little tricky but worth i
    Found this build a little fidgety and made a couple of mistakes, but not overly difficult (took just under 5hrs) most importantly my boy loves it, so all in all worth it.

    Got for my 8 year old who is pretty good with the harder Lego sets. He did need some help from his dad to build this, but has enjoyed it more than standard Lego. Fits together better and less breakable than normal Lego. He now wants more technic sets as does his older brother!

    Great produc
    Great product. Great piece to look at once completed. Our Son loved the build process! He did get frustrated at times as he’s 6 years of age so it was slightly difficult at times for him especially with the more technical areas.

    Great value for money.
    Loved this set from LEGO, it looks amazing and the building experience is great. The model looks stunning!! Great value for money. 830 pieces for 30 pounds is amazing compared to the Jeep Wrangler and Ford Mustang with each having 200 pies less than the McLaren.

    Amazing
    My 12 year son with special needs couldn’t wait for this to arrive and at a fab price, with quick delivery too. Spent the next few nights putting it together all by himself. He was so proud, as were we, when he finishesd.

    Good all round service
    A present for my grandson’s Christmas. Although not easy to construct he managed it with a little help from his dad. It’s not really a toy as such as great care must be given to handling it after the build.

    Another great Lego product.
    Another great Lego Technic product. Between my son & I we have built a few different Lego Technic models – some smaller models and some larger.

    This model is in the middle of our model sizes. Lego Technic is great – hard enough to make it challenging, but easy enough for 10-11 yr old to follow.
    Nice model, good detail. I know Lego can seem expensive, but I must say that we get our moneys worth out of the enjoyment of building. The detail means it build takes longer – we normally stop and start at it so it can take 4-5 days to complete.
    If you have never built Lego Technic before, then this is a nice starter (although some smaller models are available). If you are experienced, well then you know what to expect.
    I enjoyed this model – detail and build was just as expected.
    Definitely recommend – especially if on special offer (which it frequently is).

    It’s a great present for every moto fun (not just kid). Takes a bit more time to assembly but it’s worth it.

    Good value for money and prompt delivery
    My Husband having done all of the adult cars had this for Christmas. His opinion, good but seems more fiddly than the previous ones. Passes the time in lockdown well.

    Perfect for adult lego lovers.
    Bought this on a whim when on a deal as an extra surprise gift for my 21yr old car mad son, as he always loved lego. I got a bike version for his twin brother. Christmas day was like old times, with them spending the afternoon building with lego! Intricate enough to be absorbing, fun to do, and a lovely display piece, but I must admit I probably wouldn’t have paid the full normal price. They, however, voted the lego their best gift of the day!
