What scanner to buy

Help please . I want to buy a diagnostic scanner for my 2000 1.6 mx5 but am confused by choices. Can someone advice please? The plug is on the right hand side of the engine and scanners from my local garage will not fit

I presume your car doesn’t have the OBD connector fitted to later models. In which case you want this …

or the expensive option

See Diagnostic light codes for an example on using the LED

Many thanks for the two replies so far and both said the same and I will get the bits next week. My little car did not take to a long lockdown very well…
